    • A nickel catalyst comprising 0.1 to 12.5 wt. % of at least one structural promoter, selected from the group of oxides of metals and metalloids and combinations thereof, and 87.5 to 99.9 wt. % nickel, calculated on the weight of nickel and the structural promoter together, the catalyst having an nickel surface area, as defined herein, of at least 10 m2/g catalyst and an average pore diameter, as defined herein, of 10 to 60 nm. It has been found that already very small amounts of promoter improves the structure of the catalyst. High amounts still provide a stable, sinter resistant material, but result in a decrease in the pore size to lower levels. Furthermore, properties and sulfur uptake capacity.
    • 包含0.1至12.5wt。 %的至少一种结构促进剂,选自金属和准金属的氧化物及其组合,以及87.5至99.9wt。 按镍的重量和结构促进剂一起计算的镍含量为镍,表面积如本文所定义的至少10m 2 / g催化剂的催化剂和平均孔径为10至60nm 。 已经发现,已经非常少量的助催化剂改善了催化剂的结构。 高量仍然提供稳定的耐烧结材料,但是导致孔径降低到较低水平。 此外,性能和硫吸收能力。
